Legally?? You'll get the answer to that from the judge with your evidence suppression motion[s]. In a party / public nuisance situation, they can certainly investigate potential crimes. They can if you let them by not clearly refusing entry and search. Your word versus theirs in court. When arrested or charged with any crime, the proper questions are, can any evidence obtained in a search or confession be used against you, and can you be convicted, and what can you do? If you were cited or arrested, raise all possible defenses with whatever admissible and credible witnesses, evidence and facts are available for legal arguments, for evidence suppression or other motions, or at trial. Effective plea-bargaining, using those defenses, could possibly keep you out of jail, or at least dramatically reduce it. If you don't know how to do these things effectively, then hire an attorney that does, who will try to get a dismissal, diversion, reduction or other decent outcome through plea bargain, or take it to trial if appropriate. If serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me. Ill be happy to help use whatever defenses there may be.
